Two completely separate drop tables here, doesn't seem to be used for any non-goblins. Based on ~300 kills of each from http://www.bishopd.com/mainpages/games/rsc/drops/rsc_drops.html#begin and also the OSRS data, which is very similar for the Level 13 ones, and fairly similar for Level 7. ʞooɔ 22:23, 3 May 2020 (UTC)
Map is currently incorrect for the second set of level 19 Goblins. In replays none of the goblins are level 19/24 in this area. There are, however, level 7 and 13 goblins.
